A card which is designed to be plugged into the CPU Fast slot of the
A4000 or A3000. This card was generally shipped as the standard
processor board for 030 based A4000's and usually contained either an
030 (with MMU) or EC030 (no MMU) running at 25Mhz. Commodore had
originally also considered shipping A4000's with an 020 specification
however this never happened and so any versions of this card (if there
are any) containing an 020 are likely to be prototypes or from a demo
machine. The A3200/A3400 printed on the PCB actually refers to the
machine the card was to be installed in. Apparently Commodore actually
considered calling the 020 based A4000's the A3200 and 030 based
A4000's the A3400.
